Magda Stożek: Say goodbye to implicits - contextual abstractions in Scala 3 [Scala Days 2025]

The podcast delves into the redesign of implicits in Scala 3, prompted by the presenter's initial struggles with implicits in Scala 2. It highlights the problems with the implicit keyword being used across various language constructs, making it difficult for newcomers. Scala 3 addresses these issues by introducing specific language constructs like 'given' and 'using,' each designed for a single purpose. Use cases such as providing context, adding functionality to types with extension methods, defining type classes, and implicit conversions are explored. The discussion also covers the new import syntax, anonymous givens, and improved compiler errors in Scala 3, all aimed at enhancing code clarity and developer experience. The presenter also touches on migration strategies, noting the interoperability between implicits and the new constructs.
